x=7, see below for how.

Explanation:

First let's simplify the numerical side or the right side.

40+4 = 44

So we can write this on the right side. On the other side we just need to combine like terms, in this case the x variables.

We have 2x and 5x together on the same side, so we can add them, or add their coefficients to get the following:

2x+5x = 7x

After this we can get rid of the -5 on the left side by adding 5 to both sides.

(7x - 5) +5 = 44 +5
7x = 49

So now comes time for solving. We divide each side by 7 to get the following:

(7x)/7 = 49/7
x=7

Hope that helps!
